Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed Mayl23, 1916. Serial No. 99,297.

To all whom it may concern:

Be it known that I, ALFRED ROCK, a citizen of the United States,residing at lVilkinsonville, in the county of Worcester and State ofMassachusetts, have invented cer tain new and useful Improvements inLoom Shuttle-Threading Eyes, of which the following is a specification.

My invention relates to loom shuttles, and particularly to the threadingeye, combined with the delivery end of the shuttle.

The object of my invention is to provide an improved threading eyeforloom shuttles, and my invention consists in certain novel features ofconstructionof my threading eye, as will be hereinafter fully described.

Referring to the drawing Figure 1 is a plan view of the threading end ofa loom shuttle, with my threading eye combined therewith, and shown bybroken lines; the tip end of the spindle, with a bobbin thereon is shownin the shuttle.

Fig. 2 is a side view of the end of the shuttle shown in Fig. 1, lookingin the direction of arrow a, same figure.

Fig. 3 is a section, on line 3, 3, Fig. 2, looking in the direction ofarrow Z), same figure.

Fig. 4 is a section, on line 4, 4, Fig. 1, looking in the direction ofarrow 0, same figure.

Fig. 5 is a plan view of my improved threading eye.

Fig. 6 is a rear side view of the threading eye shown in Fig. 5, lookingin the direction of arrow 0?, same figure.

Fig. 7 is an end view of the threading eye shown in Fig. 5, looking inthe direction of arrow 6, same figure, and,

Fig. 8 is a section, on line 8, 8, Fig. 6, looking in the direction ofarrow f, same figure.

In the accompanying drawing, 1 is the threading end of the shuttle body,of any ordinary type, and having a central longitudinal recess 2 thereinfor the spindle 3,-

and the bobbin 4 on the spindle, with the thread 4 leading off from thebobbin. 5 is the thread recess, of circular shape. 6 is a verticallyextending slit in the upper side of the shuttle, leading from the threadrecess 5 and extending to and leading into the horizontal slot 7 in thefront side of the shuttle, see Fig. 2.

Extending transversely through the shut tle, just beyond and connectedwith the thread recess 5, is an opening 8 for the threading eye.

All of the above mentioned parts may be of'the usual and well knownconstruction in loom shuttles.

I will now describe my threading eye, which is combined with thetransverse opening through the shuttle.

The threading eye 9, shown detached in Figs. 5, and 6, is ofnon-circular shape in cross section, preferably square, with itsdischarging end preferably slightly tapered and rounded. The threadingeye 9 is made in this instance solid at one end, and has a centrallongitudinal or axial opening 9 in its other end. An opening 9,preferably of circular shape, leads into said opening 9 from the top'side of the threading eye. A slit 9 extends in a diagonal directionthrough the rear side of the threading eye, see Fig. 4, and connects theopening the central longitudinal opening 9, said slit communicating withor leading into both of said openings so as to allow the thread, in thethreading of the shuttle, to pass through said slit 9 and into theopening 9, and into the central opening 9, and out through thedischarging end of said last-named opening, as shown in Figs. 1, 2, and3.

The threading eye 9 is combined with the shuttle body, by inserting theslightly tapered end thereof, with the opening 9 on the upper side ofthe threading eye, into the transverse opening 8 through the shuttlebody and which opening is preferably of circular shape, and driving orotherwise forcing the threading eye into said opening 8 in the shuttlebody, from the end of said opening 8 at the top of Fig. 3, until theopening 9 in the threading eye is opposite the thread recess 5 and is inalinement with the inner end of the vertically extending slit 6 in theshuttle body, as shown in Fig. 3. The longitudinal opening 9' in thethreading eye preferably extends from the thread exit or discharge endof said eye inward part way through said eye or to the top opening 9,thus leaving the other end of the body of said eye solid so that it willwithstand the driving impact necessary in forcing said non-circular orsquare eye into the round transverse opening 8 in the shuttle body inwhich it will be held so tightly that it cannot become loosened.

9 with- The loose end 4' of the thread on the bobbin 4 is then drawnacross the thread recess 5 in the shuttle body (which recess eX-' tendsdown to the transverse opening 8) and into the vertical and horizontalslits 6 and 7 in the shuttle body, and passes into the diagonal slit 9in the threading eye 9, and through said diagonal slit into the topopening 9, and the central opening 9, and out of the discharging end ofthe threading eye, in the usual and well known way, and as shown inFigs. 1,2 and 3 of the drawings. This threading operation is possibleowing to the fact that the horizontal slit 7, which communicates withthe vertical slit 6, is in the horizontal plane of the opening 8 and thethreading eye 9 therein.

The advantages of my improved construction of a threading eye for loomshuttles,

will be readily appreciated by those skilled in the art.

The threading eye may be made from a block of solid metal, ofnon-circular shape, and preferably square, in cross section, and theopenings 9, and 9 therein bored out, and the diagonal slot 9' preferablysawed out, to make the complete threading eye; the discharging end ispreferably rounded. If preferred the threading eye may be pressed out ofsteel, or other metal.

The expense of making my threading eye is much less than the expense ofmaking the ordinary threading eye.

My improved threading eye, having a solid holding part of rectangular orsquare form in cross section, will be rigidly held in the transverseopening through the shuttle body, which may be of the usual circularshape, and it will be prevented from turning,or working loose therein,all as will be readily understood by those skilled in the art.

It will be understood that the details of construction of myimprovements may be varied if desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. The combination with a loom shuttlehaving a transverse opening, of a threading eye fixed tightly in saidopening and comprising a solid holding part which is rectangular incross section, and a tubular part having top and axial openings andhaving also a diagonal slit communicating with said top and axialopenings.

2. The combination with a loom shuttle having a transverse opening, of athreading eye fixed tightly in said opening and comprising a solidholding part which is square in cross section, and a tubular part havingtop and axial openings and having also a diagonal slit communicatingwith said top and axial openings.
